Daniel and Tamara: Stay

The new couple revealed there was lots of romance on their honeymoon. However he also revealed concerns, saying he was "Worried she would become more of a friend than my wife." We're wondering if his meeting with Jess the night before could be a reason for this.

Despite this, the couple both wanted to work on their connection.

"I want to learn more, so I decided to stay," revealed Tamara, as Dan also decided to continue in the experiment.

Ning and Mark: Stay

After admitting to both be bad at romance, the two took a step forward with flower shopping. Ning revealed that there were a lot of things in Mark that she was attracted to – his smile, his laughs and his independence.

"I was very upset," began Cyrell. "I turned into a monster that I've hidden for several years. I was very very angry to the extent that I attacked Martha," admitted Cyrell, fighting back tears. The event rocked the previously strong couple.

The experts were proud of Cyrell for accepting responsibility – but it wasn't enough to save their marriage. Nic opted to leave, saying he'd "been pushed a bit too far." Cyrell opted to stay in the experiment, despite saying she "didn't blame him (Nic)" for his decision. We'll soon find out if the couple can turn things around in the homestays.

Melissa and Dino: Leave

Dino kicked off his time on the couch by apologising: "I recorded a conversation that happened between her and her sister. It was a bad idea to start with, and I'm sorry."

But what followed the apology was Dino's recount of the recording, and as he threw some subtle shade, Mel was ready to attack. "I'm sorry Dino you're acting like I slept with your best friend and killed your dog… It was nothing you hadn't heard before."

"Please get that recording out because I am so sick of you playing the victim," added Mel. After a long tirade, the experts had to step in to get their decision.

"I'm too small. I have no balls. I'm strange and I'm just not a man," said Billy, revealing the hurtful things Susie had said to him. Susie denied going out of her way to hurt Billy, but after their arguments continued, John stepped in.

"Susie I'm going to jump in here," said expert John Aiken. "I can't sit here anymore and hear the way you talk. It's doing my had in. It is toxic," he added. John then called out Susie for talking down to Billy, and for talking to him like she sees herself "As being better than him."
